The APPLETON 29-200 is a 2-inch malleable iron set screw conduit coupling designed for joining sections of rigid metal conduit in electrical installations. The set screw design provides a secure mechanical connection without threads, allowing for faster assembly in the field. At 1.270 pounds, this coupling is built for durability in commercial and industrial conduit runs. Licensed electricians and electrical contractors install this fitting as part of grounded metallic raceway systems in compliance with NEC requirements.
This coupling is suited for use in commercial, industrial, and residential electrical installations where rigid or intermediate metal conduit connections are required. It performs reliably in conduit systems routed through walls, ceilings, and mechanical rooms. The 2-inch trade size accommodates standard 2-inch rigid conduit, making it a common choice on larger branch circuit and feeder runs.
Designed as an OEM-style replacement fitting for standard 2-inch rigid metal conduit systems in commercial and industrial electrical raceway applications.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits in the affected conduit run before beginning work. Set screws must be tightened to manufacturer specifications using an appropriate hex key or screwdriver to ensure a secure mechanical and grounding connection. Do not substitute set screw couplings in applications requiring threaded fittings unless the system design permits it.
